摘要

达拉斯动物园的大毒蛇(Lachesis muta)在捕食相对较大的猎物(约占蛇体重的25%)时，展示了攻击诱导的化学感觉搜索(SICS)和跟踪。较小的猎物通常是在掠食者袭击后被捕获的。基于猎物大小的兼性攻击和释放模式在任何啮齿动物食性毒蛇中都没有记录。实验一记录了猎物质量和击后抓放之间的关系。实验二表明，在大型猎物被释放后，发生了快速反应。实验三显示，大毒蛇在释放大型猎物后会跟随化学痕迹，这表明跟踪行为是这些蛇捕食的兼性组成部分。

IN THE FOOTSTEPS OF CHARLES C. CARPENTER: FACULTATIVE STRIKE-INDUCED CHEMOSENSORY SEARCHING AND TRAIL-FOLLOWING BEHAVIOR OF BUSHMASTERS (LACHESIS MUTA) AT DALLAS ZOO

Bushmasters (Lachesis muta) at Dallas Zoo demonstrated strike-induced chemo- sensory searching (SICS) and trail-following when feeding on relatively large prey (>25% of snake body mass). Smaller prey were usually held following predatory strikes. Facultative use of the strike-and-release pattern based on prey size has not previously been documented for any rodent- feeding viper. Experiment I documented the relationship between prey mass and post-strike holding or releasing. Experiment II showed that SICS occurred after large prey were released. Experiment III revealed that bushmasters followed chemical trails after releasing large prey, indicating that trailing behavior is a facultative component of predation in these snakes.
